The components of electricity networks are ageing. It is expected that within a horizon of 15 years, the performance will deteriorate significantly, while the costs for operating the networks will increase enormously. The main problem is that a significant part of the population of the assets is installed in the same period, resulting in a highly concentrated number of failures in a short time. The currently applied replacement strategy has to be revisited, in order to accommodate the effects of ageing assets: higher maintenance cos! ts, high failure rates, and a steep increase of capital expenditure (CAPEX).
Methods like long-term simulation, multi-criteria decision-making under uncertainty, critical asset identification, condition assessment, and advanced statistics for the extrapolation of condition assessments of representative samples of assets should be applied. By using these methodologies in a smart and integrated way, costs and performance can be kept at an acceptable level
The webinar includes a case study applying these methodologies in a practical case.
Increasing the efficiency and reliability of electrical installations through fast reactive power compensation

This webinar reviews the concept of reactive power and highlights problems that can occur if too much reactive power is drawn from the supply system. Depending on the load type (slowly or fast varying, small or large power loads) and the network (weak or strong networks, harmonics present or not), different phenomena can occur; from simply putting extra stress on supply cables to power outages bringing production lines to standstill. It is shown that for different applications different reactive power compensation solutions must be applied - special attention is paid to fast reactive power compensators and their use. Selecting the right solution can bring substantial (energy) savings to the users

Electricity generation and consumption must be maintained in constant balance at all times in any network. System operators typically achieve this by calling on large fossil-fuelled power stations to operate flexibly, which incurs high financial and environmental costs. With growing demand, declining fossil fuelled generation, and increasing renewables, the need for economic and low-carbon flexibility is becoming acute.
This webinar will discuss the benefits of, and the methods and opportunities for, allowing electricity consumers to participate in electricity balancing. Dr Michael Wagner will explain how a national electricity system can reduce emissions and increase supply security by harnessing demand-side flexibility. Dr Alastair Martin will then describe demand-side flexibility from the viewpoint of electricity consumers, showing how revenue can be earned with minimal disruption. Some positive and negative experiences of demand-side flexibility will be di! scussed. The webinar will conclude with some principles of effective demand-side flexibility
